Estimation 3rd grade: Estimation 3rd grade 3.4B Round to the nearest 10 or 100 or use compatible numbers to estimate solutions to addition and subtraction problems.
| estimate | estimation | add | subtract | round | number line | place value | fluently | fluency | magnitude | relative size | compatible numbers | compatible | nearest 10 | nearest 100 | rounding |
This bundle includes:
* 35 slide animated PowerPoint with student participation
* Estimation game - Students play with partners and choose to round by 10 or 100 in order to reach a goal of 1,000 points. The player closest to 1,000 without going over wins. There is an addition version and a subtraction version which can be played at different times.
* Mental Math Marathon Activity - Small group activity where students use mental math and estimation to be the first in their team to correctly match up number sentences with sums or differences. Both the addition version and subtraction version are included along with answer keys. This can also be played as a whole group activity to reduce the number of copies needed for small groups.
* Independent practice sheet. Assess the students' fluency and accuracy for using estimation to add and subtract. This practice page can be used again later to increase fluency.
I have bundled both the 2010 version of PowerPoint and the '97-2003 version to meet the needs of all customers. I have also embedded the font for compatibility issues. In order to maintain the animation features, most of the text can be edited. Clip art and background design can not be removed or tampered with for copyright purposes.
See the preview for more details.
